Eishirou Sugata

Eishirou Sugata (守形 英四郎) is a friend of Tomoki Sakurai and the president of The New World Discovery club, that the latter is roped into joining.

Appearance
Sugata is a tall young man who sports delicate white hair and blue-green eyes. He dresses in his school uniform, for those are his only clothes. He wears a pair of large, rectangular glasses. His facial expression is almost always neutral.

Background
Sugata is the president of the New World Discovery Club (新大陸発見部 Shin Tairiku Hattukenbu). He is a scientist of sorts and is currently researching the Angeloids and Synapse with Nymph's help. He lives in a tent near a river and is always seen wearing his school uniform, as he has no other clothes, and praises various European explorers such as Magellan and Columbus.

He is highly eccentric and has some past involvement with Mikako's family; her servants call him "young master". He is also equal on combat abilities with Mikako Satsukitane. He and Daedalus frequently work together when he is visiting Synapse. Eishirou's intellect actually impresses the Sky Master himself.

He acts like a presenter of sorts at the beginning of most episodes in the anime, usually going on about the new world, and using various examples to explain his ideas, including historical figures. These presentations typically give small hints to the events of the episode.

Sugata had an older brother whom he looked up to. Sugata's older brother had a strong passion for flight and gliders, thus, Sugata developed similar interests. Sugata always followed his older brother around, and helped him with his various projects. One day before a test flight, Sugata and his older brother had an argument over something trivial. Sugata was left to prepare the glider while his older brother was occupied. Since Sugata was still heated from the argument earlier, he put minimal effort into preparing the glider, of which he would soon come to regret. Sugata's older brother plummeted to his death when one of the wings broke off the glider due to Sugata's lack of sturdy preparation. With the responsibility of his older brother's death on his shoulders, Sugata was disowned by his family. Sugata's older brother was supposed to be the heir for head of the family, but with his death and Sugata's disowning, Sugata's younger brother became the heir. Sugata set his sights on the new world as a personal way to atone for the responsibility of his brother's death.

Plot
Eishirou Sugata is introduced in the Sora no Otoshimono manga and anime when Tomoki and Sohara arrive to school and find a massive crowd of panicking students who are looking up towards the top of the highest building on campus. Sugata appears on top of the school building with a glider, ready to jump. He checks the weather and makes the leap, but it falls between the trees and wonders whether it was a miscalculation or weight. He returns to the clubroom, and shortly afterwards Tomoki and Sohara appear asking for an explanation for the dream that Tomoki was having. He introduces them to the "New World", a black hole of sorts that has appeared above the city and invites Tomoki to investigate it that night. He is unable to attend due to Mikako kidnapping him but warns Tomoki to run away from there.

Since the black hole will be directly over the city of Sorami that evening, Eishiro arranges for the three of them to meet up at a special location just outside of Sorami so that they can witness it passing over them at midnight, but problems arise in this plan. Sohara is not allowed to go out past a certain time at night by her concerned parents, and Eishirou gets tangled up with the enraged Principal over the glider stunt that he pulled earlier in the day, resulting in Tomoki being the only one to be at the scheduled meeting place as the midnight hour draws near. Frustrated that no one will be showing up at the designated time, Tomoki plans to leave the meeting place, but is distracted when he receives a desperate call from the panicking Eishirou, who is racing over to the meeting place as fast as he can pedal his worn out bicycle.

Eishriou begins to warn Tomoki of a sudden increase in disturbance from the orb, but is cut off by the loss of the signal when the orb moves directly over the slumbering city of Sorami.

Eishirou finally arrives at the destroyed hillside that was to be the meeting place for watching the orb pass over, and is stunned to find a grimy Tomoki lying underneath a strange girl with wings emerging from her back. Freaking out, Tomoki gets out from underneath the mysterious girl that has introduced herself to him as the Pet-Class Angeloid Ikaros and has bonded to him to become his servant by the chain hanging from her collar. Interested in this development, Eishirou studies Ikaros as Tomoki demands to know how he can remove the chain that is wrapped around his right hand. Prodding at the thick chains, Eishirou deems that it would take a long time to remove it, and asks Tomoki if he lives with his parents. Tomoki responds that he lives alone in his parent's old house in the aftermath of them leaving on a world tour six years ago. Eishirou tells him to go home and get some sleep, for they will try to puzzle out the meaning of these developments tomorrow at school since his theory regarding a new world has been confirmed with the arrival of Ikaros.

In the aftermath of Tomoki's wild rampage that is corrected by Ikaros after he wishes that none of what had happened that day was real and was just a dream, Tomoki wakes up and is somewhat surprised to find the curious Ikaros on top of him, looking at him with an unsure expression. Going downstairs after Sohara brutally delivers her karate chop to him after she entered his room and found Ikaros on top of him, Tomoki is stunned to find Eishirou Sugata sitting casually at his table, eating a bowl of soup for breakfast as he looks over one of the few old Transport Cards that Ikaros still possesses. Ikaros explains to them that these older model cards have the same powers as the advanced model she used to have, but once the older cards are used on a particular desire, it cannot summon anything from Synapse other than anything else other than the original desire. She also tells them that some older cards have unique abilities that can have unsuspecting side effects, no matter what they are used for. Realizing that they are going to be late for school, Eishirou and Sohara race off towards Sorami High, while Tomoki gets roughly halfway there before realizing that Ikaros is still chained to his right hand and is flying in the air behind him, attracting the attention of the people that Tomoki is running past. Racing back home, Tomoki realizes that they need to resolve the issue of the chain binding him to her, in which she tells him that she can turn the chain invisible. Allowing her to make that change, Tomoki once again races off towards Sorami High, but has to return back to his house once again when he realizes that Ikaros is still following him closely. Telling her that she has to stay at home while he is at school, Tomoki races off towards school, now quite late for his classes as the silent Ikaros sits on the mat in the center of the living room, bummed over not being allowed to follow her master.

Tomoki accidentally "wishes" for Sohara to wear different panties other than the one with the dog icon that he accidentally sees when she falls over. This results in every pair of panties she tries to put on shooting off and flying away. Eishirou is forced to lend his club-room for her use as they try to figure out as to why this is happening. Tomoki, beaten and battered from the series of brutal chops that Sohara smashed him with after she discovered that he was the reason for her embarrassing plight, tells the concerned Eishirou that the Transport Card in his pocket had activated after he had seen her panties and thought that she would be better off with different ones, thus accidentally activating the card.

Astraea Arc
Sugata cares for Astraea as he gives her snacks. He also gave her a place to stay at temporarily.

Chaos Arc
He hated Chaos.

Hiyori Kazane/Return of Chaos Arcs
Sugata finds out that Hiyori is indeed an Angleloid, but his memory gets wiped out like all the others, and he forgets about her.

End Arc
He is presumably killed by Ikaros Melan while reprogramming the Rule Obelisk to take one more wish (Chapter 73). He is seen alive once again, presumably due to Tomoki's wish to restore everything to normal. (chapter 77).

Skills & Abilities
While Eishirou does not possess any special powers or talents, he does specialize in using highly advanced technology and his meticulous methods of exploration in order to not only advance his research, but to come to grips with the technology from the mysterious world of Synapse. Being quite intellectual, he puts together theories and ideas based upon his research and findings, occasionally helping out Tomoki and friends whenever they have difficulty understanding of certain situations. When Nymph introduces Eishirou to some of the advanced technology that she uses from Synapse, he takes a great interest in it and begins utilizing it to further his exploration and understanding of the mysterious world of Synapse. There is one downside to his genius, however, and it pertains to the fact that some of his methods or ideas usually result in negative side effects for himself or the hapless Tomoki, who falls victim to Eishirou's incorrect logic and intellectual abilities, Eishirou has shown to be quite a good fighter, managing to take down a bear when they went camping.
